How does a sand making machine work

The method is slow because the sand is rammed in layers, and it is difficult to gain uniform density. More uniform results and higher production rates are obtained by squeezing machines. Hand-operated squeezers were limited to small molds and are now obsolete. Air-operated machines work for larger molds and are also much quicker. Squeezer molding machines produce the greatest sand density at
